This is the third magical instalment in the Drákon series preceded by The Smoke Thief and The Dream Thief. Hidden among the remote hills of eighteenth-century England lives a powerful clan of shape-shifters who've become the stuff of myths and legends. They are the drákon - supersensual creatures with the ability to turn from human to smoke to dragon. Now a treacherous new enemy threatens to destroy their world of magic and glittering power.For centuries, they thought themselves alone at Darkfrith, but the arrival of a stunning letter from the Princess Maricara sent from the Carpathian Mountains of Transylvania suggests the existence of a lost tribe of drákon. It is a possibility that the Alpha lord, Kimber Langford, Earl of Chasen, cannot ignore. For whoever this unknown princess may be, she's dangerous enough to know about the drákon's existence and where to find them. That, as Kimber can't help but concede, gives her a decidedly deadly advantage. And, indeed, it wouldn't be long before Maricara breached the defences of Darkfrith and the walls around Kimber's heart.But the mystery of the princess's real identity and the warning she has come to deliver, of a brutal serial killer targeting the drákon themselves, seem all but impossible to believe until the shadowed threat that stalks her arrives at Darkfrith, and Kimber and Maricara must stand together against the greatest enemy the drákon have ever faced.
